Water Pollution
Water pollution, resulting from the discharge of harmful substances like industrial waste, agricultural runoff and plastic debris, poses a severe threat to aquatic ecosystems and human health.

Furthermore, Kutcha drains running into the canals and rivers cause water pollution. Clean water is safe for use but polluted water is harmful for man. Water pollution can be prevented in many ways.

However, it is important to note that water is life, but polluted water causes death.
